TRANSPORT OF DREDGED MATERIAL TO OYS1~R BAY REGIONAL SHORELINE PARK The dried dredged material would be transported by truck to Oyster Bay Regional Shoreline Park (Oyster Bay). Due to development of the Citation property, the City is limited to one haul route. The haul route would direct truck traffic from the DMMS around the south end of the golf course, north on the Bay Trail, east on Marina Boulevard, north on Doolittle Drive, and west on Davis Street to Oyster Bay. Trucks would return from Oyster Point to the DMMS via Fairway Drive to reduce traffic on Marina Boulevard. A haul route that is under consideration by the City for future oflhaul from the DMMS (estimated 2007) consists of constructing a temporary bridge at the south end of Doolittle Drive, across the Flood Control Channel and into the DMMS. Under this haul route alternative, trucks would bypass the Marina Boulevard and Fairway Drive residential areas by crossing the temporary bridge, travel north on Doolittle Drive and then west on Davis Street to Oyster Point. Figure 4 shows the current proposed truck haul route. TRANSPOI'T,9 TIONL OCISTICS Initial estimates are that trucks would move approximately 1,500 cubic yards during a 9-hour work day. No hauling would occur on weekends or holidays, except under unusual circumstances. Haul trucks would be prohibited from using San Leandro City streets on weekdays between 5:00 p.m. and 8:00 a.m. Under optimal conditions, all the material could be removed in approximately 60 working days. Construction is anticipated to begin on or around June 16, 2004 and extend to approximately August 9, 2004, dependent in large part on the weather. During the operation, assuming a truck capacity of approximately 16 cubic yards, the 80,000 to 100,000 cubic yards of material would he hauled in approximately 4,985 to 6,220 loads to the disposal site at Oyster Bay Regional Park. Return truck trips would increase total truck trips to approximately 9,970 to 12,440. The anticipated rate of truck travel would mean that, on average, 31 trucks would be needed per day and 21 trucks would pass any one point along the haul route during an hour (either direction j. In order to minimize distribution of dirt and dust offsite by truck traffic, all trucks would be inspected before leaving the site to ensure that no material would be tracked onto paved roads. As the material has a relatively high moisture content (approximately 50 percent), significant dust generation is not anticipated and therefore covering the trucks with tarps would be required only on an as-needed basis. Truck loading would be carefully monitored to prevent overloading. In addition, water trucks would regularly water construction areas and unpaved travel routes, and paved roads would be swept, to nunimize dust generation.
